OverviewSIMIT is a powerful simulation platform which is integrated into the SIMATIC PCS 7 engineering by means of open interfaces, but which remains open for functional expansions as a result of its modular design. You do not need to be a specialist to gener-ate and apply simulations with SIMIT. It is merely necessary to use SIMIT’s graphic user interface – all mathematical and IT pro-cedures of a simulation are carried out by SIMIT in the back-ground.
As a platform for virtual commissioning of SIMATIC user soft-ware, SIMIT provides a wide range of performance: For exam-ple, SIMIT can be automatically configured for signal tests, or it can be used to simulate processes and complete plants of any complexity in real-time. SIMIT provides the appropriate simula-tion environment, from simple key-triggered PLC signal tests, testing of the drive level, physical simulation of the process re-sponse for a complete plant test, all the way to operator training.
SIMIT is designed such that its functionality and scope can be specifically adapted to individual requirements. The basic sys-tem already provides powerful simulation functions. Hardware and software modules can be used to specifically expand the SIMIT functionalities.
Simulation is supported by appropriate automated functions. For example, importing of a symbol table or a list of signal names is sufficient for automatic configuration of the signal links. If the Im-port/Export Assistant (IEA) is used in SIMATIC PCS 7 projects, the IEA data can be used in SIMIT for automatic establishment of a simulation environment. The standard patterns suitable for SIMATIC PCS 7 are already included in SIMIT.
Note:
SIMIT can be used together with SIMATIC PCS 7 V5, V6 and V7.

FunctionA simulation is produced with SIMIT simply by "combining" indi-vidual components on a GUI. The predefined components are selected from a library, connected together, and parameterized.
Engineering on the PC with SIMIT
The SIMATIC user program generated in SIMATIC PCS 7 is loaded into the PLC simulation S7-PLCSIM, and receives the simulated I/O signals from SIMIT via the PLCSIM coupling. The interface is configured automatically in SIMIT by importing the symbol table from SIMATIC PCS 7. SIMIT can also generate the corresponding simulation environment automatically using the PCS 7 Import/Export Assistant (IEA). Simulation examples matched to example automation solutions are used for this. The complete interaction between automation and process (model) is completed by means of a process model.
If the SIMATIC PCS 7 operator station is coupled to PLCSIM, the complete automation function from the sensor to the automation and visualization systems and back again to the actuator can al-ready be tested on the SIMATIC PCS 7 engineering system in the technical office without the actual existence of the automa-tion hardware.
Factory Acceptance Test (FAT) of the overall plant with SIMIT The Factory Acceptance Test (FAT) tests the complete automa-tion funcautoma-tions. The actual automaautoma-tion systems (SIMATIC S7 con-troller) are loaded with the SIMATIC user software. SIMIT then simulates the input/output signals, instrumentation and field de-vices. The simulation values are transmitted as PROFIBUS DP telegrams to the individual automation systems via the SIMIT in-terface modules (IM-1, IM-2). The link between SIMIT and the automation level is carried out automatically by the SIMATIC PCS 7 hardware configuration. As already described for engi-neering on the PC, the IEA mechanisms can also be used to au-tomatically generate the test environment. If SIMIT handles the process simulation in addition, the FAT then becomes a plant test. Commissioning can already be carried out in the virtual pro-cess in an early phase of the project.

Training simulation with SIMIT
In conjunction with SIMATIC PCS 7 and S7- PLCSIM, SIMIT forms the simulation platform for a training system. Plant opera-tors can then be trained even before the real plant is fully func-tional.
The simulation models used provide a realistic plant response under various operating conditions (e.g. start-up and shutdown, safety-related shut-down, etc.). If necessary, special simulators can also be linked to SIMIT via the standardized OPC cli-ent/server coupling.
Additional features
Apart from the standard library, FlowNet provides a comprehen-sive library for simulation of material flows in single-material sys-tems. Individual library components or macro components can be created using editors. SIMIT’s scope of performance is rounded-off by animated, user-configured graphics as well as trend windows for visualization of simulation values.
